IMPROVEMENT- IN BARREL-FILLERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it may concern Be it known that I, Lewis H. WATSON, of the city of Pittsburg, in the county of Allegheny' and State of Pennsylvania, have invented an Improved Barrel- Filler; of Which the following is a full, clear, and eX- act description, reference being had to the accompanying drawing making a part of this specih'oation, in which- Figure l is an external view of my barrel-filler;

.Figure 2, a vertical central section through the section liner@ D of lig. 3;

Figure 3, a horizontal section through the section line A B of fig. l; and

Figure 4, a horizontal section through the section line E F of iig. 2.

Similar letters of reference in the drawing indicate like parts.

H G represent the cylinder or tube through which the liquid flows into the barrel, and which is internally divided into two chambers by the valve-seat T.

Near the center of the lower part G there are two lugs, M', cast, so as to prevent the tube frompassing too far into the barrel.

In the upper chamber H is placed the valve S, which is pressed upon its seat T by the spring U.

Around the valve is a number of guides, H', so as to hold it in place, while just above it is a removable cap, J, large enough to allow the valve to be removed, and which has a hole drilled in it, so as to receive the end of the valve-stem.

In the chamber G is placed a smaller tube, P, open at `its lower but closed at its upper end, and in which is suspended the oat O.

'Io the upper end of this lloat is secured a rod, c, which has its other end attached to the lever N extending outward at right angles to it.

To the side of the chamber G is cast an ear or projection, M, to which the lever N is pivoted at the point c, and which is provided with the pin f, upon which the lever N rests.

The outer end d ofthe lever is turned at right angles, and has a notch cnt in its top so as to catchand hold the end of lthe handle L.

This handle is secured to the outer end of the shaft L by the screw It, and has a small vertical slot, b, in its side, so that thc end of the handle can be raised Vfrom the catch d before it begins to turn.

To the side of the handle is secured, by means of the clamp W at the point z', the fiat spring Y, so as to cause the end of handle to press against the catch rl, and in order to regulate this pressure I employ the set-screw a', which extends throngh'the handle, as shown in fig. 1.

The lower end of the handle is made V-shaped, so as to make it the more easily slip from the catch d.

The inner end of the shaft L has the crank R attached, and to this crank is secured therod R', for the purpose of raising the valve from its seat.

In the side of the pipe P is cut a slot or opening, P', as shown in g. 4, greatly enlarged at its top, so as to allow a free escape of the air from the barrel as it is being driven ont by the fluid.'

K is a sleeve surrounding the shaft L, screwed into the upper part of the chamber G at h, and provided with a stuiiing'- box, g.

vAround the end ofthe shaft is a coiled spring, V, so as to prevent any movement endwise.

The pressure in the source of supply is always varying, dependent upon the quantity contained therein.

When the tank is nearly empty there will be but a Very slight pressure upon the valve S, but when full a very heavy one. This varying pressure causes friction on the shaft L, making it more or less difficult to be released from the catch d.

When the supply-tank isfull the friction is so great thatit isy veryditficult to regulate the handle so that it will be released from the lever at the proper moment, and the consequence is that the barrel often fills and runs over.

In order to make this friction always the same upon the end of the handle, I cnt the slot b in its side, so as to allow it a slight vertical movement just sutiicient to clear the catch before it begins to turn; the spring Y, as soon as the end of the handle is released, throws it upward and away from the catch.

The operation is as follows:

A piece of tubing, connected to the supply-tank, is placed over the inlet-tube I, and the lower end of the tube G placed in the barrel to be filled. The handle L is then turned around until its end catches in and is held by the catch d.' In turning this handle the shaft L is made to partly revolve, and in doing so the crank R causes the rod R to lift the valve S from its seat, and to hold it suspended, so as to allow the fluid to pass freely into the barrel.V As soon as the duid has lled the barrel it rises into the tube P, and acting on the float O raises the end of the lever N so as to release the handle L' from the catch d. As soon as the end is released the spring Y throws the handle around, drawing the crank R downward, and allowing the spring U to instantly close the valve so as to stop the flow of the fluid.

By means of the set-screw a the hold of the end of the handle in the catch d can he made so sensitive that it will be released as soon as the liquid reaches any desired point on the float.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

l. In apparatus for iilling barrels, the slot P' in the tubes G and P, made to form a. communication with t'nenterior of the barrel and the air without for the escape of the air from the barrel, and also to admit the free play of the outside tripping-lever N, as described.

2. A turning handle, L', having a tripping-arm, z, in combination with a cranked spindle, L, the tripping-lever N, and float O, as described.

3. The turning handle L'land its arm z, in combinartion with the spring Y, its regulating-screw a, and the tripping-lever N, as described.

4. In abarrel-lling apparatus, in which Vits cut-off valve S is operated by a turning spindle, L, having both a crank, R, and handle L' tripped by the action of a float, the said handle L made to have a movement independent of its spindle L and in advance of the action of the valve S. to allow the turning handle and 'tripping-lever to be tripped without regard to the l 6. The combination of the turning handle L', spring Y, regnlating-screwa, tripping-lever N, float O, Asprn g valve S,erank R, crank-rod R', spindle L, tube G with its air-communicating slot P', and the oat-tube P, the several parts being constructed, arranged, and operating as described.
